Answer:

Evolution Genetics

Explanation:

Genetic evolution of living beings is the process of the disappearance or emergence of new species due to genetic variability. This process is very slow and can take up to thousands of years so it is difficult to keep up with the evolution process.

The research shown in the question above is an example of genetic evolution research. This is because antibiotics are substances that have the power to kill any kind of bacteria, however some bacteria evolve, new species of bacteria have emerged that have the ability to resist and survive the action of antibiotics.

Proteus vulgaris has a doubling time of roughly 28 minutes. If an initial population of 500 cells is allowed to grow for 6 hours

romanna [79]

<u>Answer:</u> The final population of Proteus vulgaris after 6 hours is $3.71\times 10^{6}cells$

<u>Explanation:</u>

We are given:

Proteus vulgaris divides and doubles every 28 minutes

Total time given = 6 hours = 360 min (Conversion factor: 1 hr = 60 min)

Number of times Proteus vulgaris doubles in 6 hours = $\frac{360min}{28min}=12.857times$

Calculating the number of bacteria after 6 hours under ideal conditions:

We are given:

Initial population = 500 cells

Number of times it doubles = 12.857 times

Final Proteus vulgaris population = $500\times 2^{12.857}=3709476.8=3.71\times 10^{6}cells$

Hence, the final population of Proteus vulgaris after 6 hours is $3.71\times 10^{6}cells$
